Abstract

Tirtayasa Beach is a coastal tourism attraction in Bandar Lampung City, located in Way Tataan Village, East Teluk Betung District. The waters of Tirtayasa Beach have significant tourism potential due to their natural beauty. However, a decline in water quality, caused by increased human activities and domestic waste input around the beach, has affected the physical, chemical, and biological conditions of the waters. Mollusks can serve as indicators of water quality. Therefore, the structure of the mollusk community can be used to assess the condition of these waters. This study aimed to evaluate the structure of mollusk populations and analyze the influence of water quality on mollusk communities in the intertidal zone of Tirtayasa Beach, East Teluk Betung District, Lampung. The selection of study locations/stations and observation points was carried out using the purposive sampling method. The mollusks identified in the waters of Tirtayasa Beach belong to two classes: Gastropoda and Bivalvia. The Gastropoda class, with eight species, dominated across the three stations, with Cerithium kobelti being the most prevalent species. The parameter that significantly affected mollusk abundance at Station 1 was pH. At Station 2, depth, brightness, dissolved oxygen (DO), and salinity were influential. At Station 3, total suspended solids (TSS) and temperature were the key influencing factors.  Keywords: Abundance, biodiversity, evenness index, principal component analysis.

Abstract

Pulau Sebesi di Kabupaten Lampung Selatan memiliki potensi besar untuk pengembangan wisata bahari berkelanjutan karena kekayaan ekosistem laut, topografi unik, serta letaknya yang strategis dekat Gunung Anak Krakatau. Meski demikian, pengelolaan wisata di pulau ini masih menghadapi berbagai hambatan, seperti kurangnya infrastruktur, rendahnya promosi, dan belum adanya perencanaan berbasis data. Penelitian ini bertujuan mengevaluasi atau menilai tingkat kesesuaian lahan untuk kebutuhan wisata pantai sekaligus merancang strategi pengembangan yang sesuai. Metode penelitian yang diterapkan adalah deskriptif dengan menggabungkan pendekatan kuantitatif dan kualitatif. Pengumpulan data melalui observasi langsung serta wawancara kuesioner. Analisis data dengan pengukuran Indeks Kesesuaian Wisata (IKW) dan analisis SWOT dengan matriks IFAS dan EFAS. Nilai IKW pada Stasiun 1 tercatat 2,245, Stasiun 3 sebesar 2,415, dan Stasiun 4 sebesar 2,32, ketiganya termasuk kategori sesuai. Sementara Stasiun 2 sebesar 2,9 termasuk kategori sangat sesuai. Berdasarkan SWOT, Pulau Sebesi berada pada kuadran III. Hal ini berarti strategi yang direkomendasikan adalah WO (memanfaatkan peluang dengan mengurangi kelemahan). Strategi pengembangan yang diusulkan meliputi peningkatan promosi digital, pelatihan sumber daya manusia lokal, dan kolaborasi multipihak untuk perencanaan pengelolaan terpadu. Hasil kajian menunjukan bahwa Pulau Sebesi berpeluang besar menjadi destinasi ekowisata unggulan jika pengelolaannya diarahkan secara tepat dan partisipatif.

Abstract

Megalaspis cordyla, locally known as ikan bekre, stands as a crucial economic species commonly consumed by the people of Lampung. The escalating demand for this fish has significant implications for increased fishing activities, potentially impacting its population. This research aimed to explore the biological characteristics of M. cordyla landed at the Lempasing Fishing Port, Bandar Lampung, providing fundamental insights for fisheries resource management in the waters of Lampung Bay. Using a quantitative descriptive method, the sampled fish has been analyzed to get size structure, growth type, and fish condition factors based on length and weight data collected from M. cordyla landed weekly. Between April and June 2022, a total of 300 samples were collected, with length ranging from 230 to 430 mm TL, with the largest count (77 individuals) in the 314-334 mm interval. M. cordyla has an allometric negative growth pattern in Lampung Bay, with a growth coefficient (b) value of 2.47. Fish condition factor values ranged from 0.71 to 1.33, with June having the highest average value of 1.03. This information contributes greatly to a better understanding and long-term planning for the management of this fish population.Keywords: Allometric; Condition Factor; Length-Weight Relationship; Pelagic Fish; Aquatic Resources Management

Abstract

The presence of phytoplankton greatly affects aquatic life because it plays an important role for aquatic biota. The purpose of this study was to identify the structure of the phytoplankton community, determine the condition of the waters and analyze the relationship between the structure of the phytoplankton community and the physical and chemical factors of the waters of Lake Ranau, Lumbok Seminung District, West Lampung. This study was conducted in November 2023 - January 2024. The determination of the research station used the purposive sampling method. Phytoplankton samples were taken using a 60 micron plankton net. Analysis of the effect of physical and chemical parameters of water on phytoplankton abundance was analyzed using PCA using statistical software. The results showed that the phytoplankton found consisted of 5 classes, namely Bacillariophyceae, Cyanophyceae, Chlorophyceae, Euglenophyceae, and Zgynematophyceae. The saprobic coefficient value of phytoplankton ranged from 0.2 - 0.7. This shows that the condition of the waters in Lake Ranau, Lumbok Seminung Regency is in a state of mild to moderate pollution. Environmental parameters that are positively correlated with phytoplankton abundance are DO, brightness, current velocity, and N/P ratio. Environmental parameters that are negatively correlated are temperature and parameters that do not affect phytoplankton abundance are H2S and pH.  Keywords: Lake Ranau; Phytoplankton; Saprobic

Abstract

Blue swimming crab (BSC) is one of Lampung's main export fisheries commodities. The catch of BSC by fishermen in East Lampung waters is becoming more intensive and increasing from year to year, so it is a concern that it will threaten the sustainability of the stock. This research aimed to analyze the biology of several populations of BSC in East Lampung waters during overfishing conditions. Population biology data on BSC analyzed included growth rate, size at first caught, recruitment patterns, sex ratio, fishing mortality, exploitation level, and a potential spawning ratio. The analyzed data originated from BSC caught by crab net fishermen in East Lampung landed at TPI Kuala Penet and TPI Muara Gading Mas for 1 year (August 2019-June 2020), totaling 35,322 samples consisting of 20,586 males and 14,736 females. The research showed that the level of crab utilization had an E value of 0.71 per year. In these overfishing conditions, it was known that the growth of crabs in these waters was following the equation of CWt= 191,6x[1-e-130(t-(-0,073))]. The carapace width of BSC caught for the first time (Lc) was 119 mm (male) and 123 mm (female) with a sex ratio (M: F) that varied every month between 1:1 and 2:1. Recruitment occurred throughout the year. The SPR was slightly under 20% indicating that overfished conditions had caused the potential for the crab to spawn in an unsustainable condition.

Abstract

Along with the rapid advancement of digital information technology, various sectors are driven to adapt through innovation, including efforts to strengthen economic empowerment. Social-innovation-based sociopreneurship serves as an appropriate approach to addressing economic challenges while also generating positive social impact. This study focuses on applying social-innovation-based sociopreneurship strategies to enhance economic empowerment at Pondok Pesantren Al Hikmah Bandar Lampung, by involving women in product development activities. The research aims to introduce, reinforce, and implement economic empowerment strategies rooted in social innovation by utilizing the potential of women. The activities were carried out through six stages: (1) delivery of educational materials, (2) design of social-innovation-based marketing strategies, (3) introduction to information-technology-based marketing, (4) understanding women’s potential in marketing, (5) creation of digital marketing media, and (6) development of innovative marketing content. It is expected that this program will increase the knowledge and practical skills of women at Pondok Pesantren Al Hikmah Bandar Lampung, enabling them to optimize their roles in product development and marketing. Ultimately, this initiative is expected to foster economic independence based on sociopreneurship within the pesantren.
